“Corpus callosum agenesis–neuronopathy syndrome” describes a condition where a person is born with a missing or very under-developed corpus callosum (the thick nerve bridge that connects the right and left sides of the brain) and has damage or dysfunction of peripheral nerves (a “neuronopathy” or “neuropathy”). The brain change can affect learning, movement, coordination, behavior, and seizures. The nerve problem can cause weakness, numbness, pain, balance trouble, and sometimes problems of the autonomic nerves that control blood pressure, gut, bladder, and sweating.
This pattern can appear as part of different genetic syndromes. One well-known example is hereditary motor and sensory neuropathy with agenesis of the corpus callosum (often linked to the SLC12A6/KCC3 gene). But similar combinations can occur in other rare genetic conditions. Some people have mostly learning and coordination limits. Others have progressive weakness and loss of feeling in the limbs. Many need a tailored plan that combines therapy, assistive devices, and sometimes medicines to manage symptoms and improve daily life.
Corpus callosum agenesis-neuronopathy syndrome is a rare, inherited disorder in which two things happen together:
-
the big nerve bridge that connects the two halves of the brain (the corpus callosum) is missing or under-developed; and
-
there is a severe, progressive nerve problem in the body (a sensorimotor neuropathy) that weakens muscles and dulls feeling in the arms and legs.
The condition starts in infancy, progresses through childhood and adolescence, and is caused by harmful changes (mutations) in a single gene called SLC12A6 (it makes the K-Cl cotransporter KCC3 that nerve cells need for healthy function). Typical signs include very weak or floppy muscles in infancy, absent reflexes, slow motor development (late sitting, standing, walking), gradual loss of strength and sensation, tremor, joint tightness and spinal curvature over time, and learning or behavior difficulties in many individuals. Diagnosis rests on the clinical picture, electrical tests of nerves, MRI of the brain, and genetic testing showing two faulty copies of SLC12A6. Care is supportive (physiotherapy, mobility aids, spinal care, seizure/behavior management). NCBIMedlinePlusOrpha
Another names
This syndrome has several names used in clinics and the medical literature. The most common are Andermann syndrome, ACCPN (agenesis of the corpus callosum with peripheral neuropathy), and HMSN/ACC (hereditary motor and sensory neuropathy with agenesis of the corpus callosum). You may also see KCC3 axonopathy, which points to the gene/protein involved (SLC12A6/KCC3). Some sources use corpus callosum agenesis-neuronopathy syndrome, a descriptive label that highlights the two main problems—brain bridge malformation plus peripheral nerve disease. These labels refer to the same autosomal recessive disorder caused by biallelic SLC12A6 variants. NCBIWikipediaOrpha
Types
There is no universally fixed “official” subtype system, but doctors find it useful to group cases in a few practical ways:
1) By corpus callosum involvement:
• Complete agenesis (callosum entirely absent)
• Partial agenesis / dysgenesis (partly formed)
• Apparently normal callosum (seen in a minority, even with classic neuropathy)
This spread is well-described on MRI in published cohorts. NCBI
2) By age at motor decline:
• Classic infantile-onset (hypotonia/areflexia very early, walking achieved late, loss of walking in early teens)
• Juvenile/attenuated (slower progression but the same pattern)
3) By neuropathy profile:
• Motor-predominant, sensory-predominant, or mixed (most are mixed but severity of each component varies person to person)
4) By variant class in SLC12A6 (gene-based grouping):
• Loss-of-function (splice-site, nonsense)
• Missense / hypomorphic
Some founder variants are common in specific populations (e.g., French-Canadian). NCBI
Causes
Important note: Medically, the direct cause of this syndrome is having two disease-causing variants in SLC12A6. The list below breaks that reality into clinically meaningful “cause categories” (genetic mechanisms and risk contexts) and then lists other conditions that can cause a similar combination of brain-bridge anomaly and neuropathy (differentials)—so you see what doctors actually consider when working up a case.

Contexts that mimic or overlap the picture (differentials / look-alikes)
- Isolated agenesis of the corpus callosum (ACC) from other genetic causes (chromosomal anomalies, other single-gene disorders). This is not ACCPN, but can be confused early. NCBIrarediseases.org
- ACC from in-utero exposures (e.g., fetal alcohol spectrum, some infections), again not ACCPN. NCBI
- Inherited neuropathies without callosal anomalies (e.g., CMT subtypes), which can resemble the limb weakness/sensory loss pattern. (Clinical differential.) NCBI
- Mitochondrial or peroxisomal disorders with neuropathy plus brain malformations. (Ruled out by targeted labs/genetics.) NCBI
- Spinal muscular atrophy or congenital myopathies (motor weakness with hypotonia but different electrodiagnostics). NCBI
- Acquired neuropathies (toxic, inflammatory) that present later and lack the brain malformation. NCBI
- Other genes in the callosal-development pathway producing ACC with central (not peripheral) motor issues. NCBI
- Syndromic ACC (e.g., Aicardi in girls), different etiology and exam pattern. NCBI
Symptoms
-
Weak or floppy muscles in infancy (hypotonia): babies feel “loose” when held; this is often the first clue. NCBI
-
Absent reflexes (areflexia): knee/ankle jerks are missing on exam because the peripheral nerves don’t carry signals well. NCBI
-
Slow motor milestones: sitting, standing, and walking come very late; average walking onset is around 3–4 years. NCBI
-
Progressive muscle weakness: starts in feet/legs and hands/arms and worsens with age. NCBI
-
Muscle wasting (amyotrophy): muscles become thin over time because nerves cannot stimulate them normally. MedlinePlus
-
Reduced or lost sensation: touch and pain in a “glove and stocking” pattern fade, making injuries easier to miss. NCBI
-
Tremor: a coarse shaking of limbs that is usually due to the neuropathy itself. NCBI
-
Joint tightness and contractures: ankles, fingers, and other joints stiffen as muscles and tendons shorten. NCBI
-
Spinal curvature (scoliosis): the spine curves over time; braces or surgery are sometimes needed. NCBI
-
Cranial nerve signs: droopy eyelids (ptosis), facial weakness, problems moving the eyes; these vary. NCBI
-
Developmental or learning difficulties: ranges from mild to severe; some people have near-normal learning. NCBI
-
Behavioral or psychiatric episodes in the teens: paranoia, hallucinations, or mood changes in a substantial minority. NCBI
-
Seizures (in some): generalized, absence, or focal types may occur and are treated like other epilepsies. NCBI
-
Gait problems and frequent falls: due to weakness, poor sensation, and joint changes. NCBI
-
Breathing restriction (later): scoliosis and weak respiratory muscles can reduce lung capacity. NCBI
Diagnostic tests
A) Physical Examination
1) Comprehensive neurologic exam: The doctor checks tone (often low), strength (reduced), reflexes (usually absent), and sensory loss in the limbs. This pattern—early hypotonia + areflexia with progressive weakness and sensory loss—strongly suggests the diagnosis. NCBI
2) Developmental assessment: Standard tools measure motor and cognitive milestones. Delayed walking and mixed learning profiles are typical; these scores also guide therapy planning. NCBI
3) Musculoskeletal exam: Feet deformities, finger contractures, and scoliosis are looked for because they affect walking, pain, and breathing and may need bracing or surgery. NCBI
4) Cranial nerve exam: Eyelid droop, gaze palsy, facial weakness, and nystagmus are checked because they are common extra clues in this syndrome. NCBI
B) Manual (bedside) Tests
5) Deep tendon reflex testing: Tapping the tendon at the knee/ankle normally triggers a kick; in this condition reflexes are typically absent, confirming peripheral nerve involvement. NCBI
6) Romberg test: Standing with feet together and eyes closed exposes sensory imbalance from loss of joint-position sense; swaying or falling suggests sensory neuropathy. (Support staff should guard for safety.) NCBI
7) Vibration testing with a 128-Hz tuning fork: Reduced or absent vibration sense over ankles and toes is common and tracks large-fiber sensory loss. NCBI
8) Heel-to-toe (tandem) gait / toe-heel walking: Weak distal leg muscles and poor proprioception make these tasks hard, helping quantify motor and sensory dysfunction at the bedside. NCBI
C) Laboratory & Pathological
9) SLC12A6 sequencing: This is the key test. Finding two disease-causing variants establishes the diagnosis in the right clinical context. NCBI
10) SLC12A6 deletion/duplication analysis: If routine sequencing is negative or shows only one variant, targeted methods (e.g., MLPA) look for hidden exon-level changes. NCBI
11) Broader genomic testing (multigene panel or exome/genome): Useful when the picture is unclear or when clinicians need to exclude other rare causes of ACC or neuropathy. NCBI
12) Cerebrospinal fluid (CSF) protein: A lumbar puncture often shows a mild protein elevation, supporting a chronic neuropathy process (not specific, but helpful). NCBI
D) Electrodiagnostic
13) Nerve conduction studies (NCS): In infants and children, sensory nerve action potentials are often absent; motor responses are low in size; conduction speeds vary. This confirms a severe axonal sensorimotor neuropathy. NCBI
14) Electromyography (EMG): Shows signs of denervation (e.g., fibrillation potentials) and chronic neurogenic change, proving that the problem is nerve-to-muscle. NCBI
15) Electroencephalogram (EEG): Used if seizures or spells occur; helps classify seizure type and guide antiseizure therapy. EEG is part of the recommended evaluation set. NCBI
16) Evoked potentials (as needed): Somatosensory or visual evoked potentials may document slowed central pathways when the clinical picture is complex. (Adjunctive, not obligatory.) NCBI
E) Imaging
17) Brain MRI (childhood): The main imaging test. It often shows complete ACC (majority) or partial ACC (some), and sometimes mild cerebral/cerebellar atrophy with age. Parallel ventricles on axial images are classic in ACC. NCBI
18) Prenatal ultrasound (2nd–3rd trimester): May detect absent or short corpus callosum; prompts fetal MRI and counseling. This is standard for ACC detection in utero. Cleveland Clinic
19) Fetal MRI: Gives a clearer look at midline brain structures than ultrasound and helps confirm callosal agenesis or dysgenesis before birth. Cleveland Clinic
20) Spine X-rays (and, when needed, EOS/CT): Track scoliosis progression to plan bracing or surgery and to anticipate breathing impacts. NCBI
Non-Pharmacological Treatments
(15 Physiotherapy, plus Mind-Body, Gene-Informed Lifestyle, and Educational Therapy)
Each item includes: description (~150 words), purpose, mechanism, and benefits.
1) Developmental Physio-rehabilitation (Core Program)
Description: A tailored, long-term physiotherapy program begins in infancy or as early as possible. It focuses on posture, head/trunk control, rolling, sitting balance, crawling, standing, and walking, then advances to stair skills, transfers, and community mobility. Sessions combine task-specific practice with play-based activities to maintain motivation. Therapists use cueing, hands-on facilitation, and home programs to reinforce gains. For neuropathy, emphasis is placed on distal strengthening (ankle dorsiflexors, intrinsic foot muscles), proprioceptive training, and balance strategies (wide base, assistive devices). Stretching prevents tight calves and hamstrings; orthoses support alignment. As the child grows, conditioning and endurance training help offset fatigue. The therapist monitors for scoliosis and contractures and coordinates with orthopedics, orthotists, and occupational/speech therapists. Regular reassessment updates goals and equipment.

Frequently Asked Questions
1) Is this condition curable?
There is no single cure today for genetic agenesis of the corpus callosum with neuropathy. But many symptoms can improve with therapy, supports, and targeted medicines. Quality of life can be very good with the right plan.
2) Will symptoms get worse?
The brain difference is stable from birth. Some neuropathies are slowly progressive. Regular follow-up allows early treatment of new issues like foot deformity or scoliosis.
3) Can my child learn and attend regular school?
Many children do, with supports. An IEP, therapy, and classroom accommodations help access learning and social life.
4) Are seizures common?
Some people have seizures; others do not. If seizures occur, modern anti-seizure medicines and devices like VNS can help.
5) How is neuropathic pain treated?
Start with non-drug strategies (sleep, pacing, gentle exercise). If needed, medicines like gabapentin, pregabalin, duloxetine, or amitriptyline may help.
6) What about orthostatic dizziness?
Hydration, compression wear, slow position changes, and clinician-guided medicines (midodrine, fludrocortisone, droxidopa) can reduce symptoms.
7) Will my child need surgery?
Only if specific problems arise, such as severe contractures, progressive scoliosis, refractory seizures, or unsafe swallowing.
8) Can exercise make it worse?
Well-planned, graded exercise helps. Overexertion can flare pain or fatigue, so balance activity with rest.
9) Which brace is best?
An orthotist will match brace type to gait pattern. AFOs for foot drop are common; the fit should be comfortable with no pressure sores.
10) Are supplements necessary?
Some people benefit (omega-3, B-vitamins if low, alpha-lipoic acid). Discuss with your clinician to avoid interactions and overdosing.
11) Is stem-cell therapy recommended now?
Not for routine care. Consider only within regulated clinical trials.
12) Can this affect life expectancy?
Most people live into adulthood. Complications like falls, infections, severe scoliosis, or nutrition problems need active prevention to protect long-term health.
13) Can parents or siblings be tested?
Yes. Genetic counseling explains the gene, inheritance pattern, and testing options.
14) What home changes help most?
Declutter walkways, add grab bars and rails, good lighting, non-slip mats, and safe storage height for heavy items.
15) How often should we review the plan?
At least every 6–12 months, and sooner if new symptoms appear or growth spurts change mobility or brace needs.
